Container Number Recognition (CNR)

CNR performs reading and identification of ISO 6346 container codes, in logistic ports and handling cranes. The intelligent system allows us to manage several lanes from a single post and perform access control and efficient recognition, not only of the containers but also of the trucks in charge of their transportation. CNR is based on technologies deep learning, optical character recognition.

Intro

Based on these five stages, appropriate projects to increase and retain customers.

The customer lifecycle includes 5 below stages:

  1. Reach — claim future customers’ attention;
  2. Acquisition — bring them into a sphere of influence;
  3. Conversion — turn them into registered instead of paying customers;
  4. Retention — keep them as customers;
  5. Loyalty/advocacy—turn them into a company advocate

Reach: Traffic Profile System

No Goals Data Sources Methods Results
1 Rank leads and save time for sales team Information from browser of customers Markov chain Decision tree Saved time of sales person by 23%
2 Increase turnover rate Media information Increased turnover rate to 25%
3 Detect created leads by robots Session page information Decreased marketing expenses by 14%

Acquisition - Reactivated Leads Points System

  • Goal: Improve the overall sign-up rate of reactivated leads.
  • Data sources: landing page data, device, location, estimated age, landed time, etc.
  • Method: Random forest
  • Result: Increased sign-up rate by two times.

Conversion - Customer Renewal

  • Goals: Improve overall renewal rate; Summarise main factors; Estimate quantity and duration of phone calls during contract lifetime.
  • Data sources: class data; teacher and student data.
  • Method: Random forest (Boosting)
  • Result: Increased renew rate by up to 30%.

Retention - Customer Churn (Karma)

  • Goal: Decrease client refund rate, which will increase the Return On Investment (ROI). If a company interacting with every customer would cost a considerable amount since it needs to create possible refund lists with the estimated rate.
  • Data sources: student-customers’, teachers’ data, and data related to the product that the customer bought.
  • Methods: Logistic Regression and Random Forest.
  • Result: Decreased refund rate to 27%.

Intro

I worked for Domus Sapiens and a programmer/data analytic/project manager. Did the design and programming job of the smart systems in the intelligent building, and one individual completes a complete set of processes. The smart buildings/city I’ve done a dozen large and small, concentrated in Moscow and St Petersburg. One of the most famous and complex cases is the development of an intelligent system in Moscow City.
